Application tiled Aprill, 1892. Serial No. 429,341. (No model.)

To @ZZ whom. it may concern.-

Be it known that I, NEWTON MONDAY, a citizen of the United States,residing at Lathrop, in the county of Clinton and State ofMissouri,haveinvented a new and useful Improvement in Ohurns, of whichthe following` is a specification.

This invention relates to certain new and useful improvements in churns,and consists of the construction and arrangement of the parts thereof aswill be more fully hereinafter described and claimed.

The object of this invention is to provide a churn equipped in suchmanner as to introduce a current of air and force the same bycentrifugal, action through the particles of the cream to materiallyassist in breaking the same and the globules thereof, therebyfacilitating the formation of butter.

In the drawings-Figo re 1 is a perspective view of the churn embodyingthe invention. Fig. 2 is a transverse vertical section thereof. Fig. 3is a detail perspective view of the air feeding device removed andshowing the chamber or head thereof separated. Fig. 4 is a detailperspective view of one of the breakers. Fig. 5 is a bottom plan view ofa portion of the air-feeding device.

Similar numerals refer to corresponding parts in the several figures.

Referring to the drawings, the numeral 1 h designates a tub or churnbody which may be provided with a suitable bail2 and having on theinterior surface thereof a series of eyes 3 arranged at au angle ofinclination. On the interior surface and centrally located in the bottomof the said `tub or body 1, is a step 4 after referred to. Y

Breakers 5 are secured to the inner surface of the churn, and arearranged diagonally or spirally. These breakers consist of strips ofsuitable material having outer faces 6 beveled and curved to conform tothe inner surface of the tub or body 1, and are formed with slots 7 topermit the passage therethrough of the cream dashed upward thereagainst,when said cream iiows downward toward the bottom of the tub orbody 1. The opposite faces of these breakers are parallel and stand atan angle to the tub or body, and the lower end of each of the breakersis tapered in order to avoid unnecessary projection when mounted inposition in the tub or body. The breakers are removably connected to thesaid tub or body and are provided with catch pins S adapted to engagethe eyes 3. The cream dashed against the projecting faces of thebreakers will be forced backward as said breakers are located in line ofthe whirl of the cream.

The centrifugal air device is composed of a tube 9 having a yoke 10 atits upper end carrying a sleeve 1l through which extends a set screw 12.The upper end of the said tube is open and clear for the admission ofair thereinto, and the lower end thereof is formed, or has attachedthereto theupper section 13 of an air chamber. The lower section 14 ofsaid air chamber is a counterpart of said upper section, and is slightlylarger in diametric crosssection so as to embr'ace said upper section.Both of the sections 13 and 14 are constructed in the form of disks withflanges 15 and 16 respectively formed with each. The lower end of thetube 9 opens into the upper section 13, and the flanges of this sectionare extended inwardly as at 17 eccentrically to the center of the saidsection. Between said inwardly extended portion of the liange 15 and themain body of said flange exit openings 13 are provided in successiveposition, and between the main part of the llange 15 and the inwardlyextended portion 17 air passages 19 are provided. Adjacent to the exitopenings of the air passages 19 horizontally disposed slots 2O areformed in the main body of the flange 15, and are adapted to receivestuds 21 carried by inwardly bent portions 22 of the flange 16 on thesection 14, to thereby lock the sections 13 and 14 of the air chamber inremovable engagement with each other. Between` the inwardly bent portion22 of the liange 16 and the main body of said flange exit openings 23are also provided, which align with the exit openings of the air passage19 of the section 13 when the two sections 13 and 14 are united. Thesaid lower section 14 of the air chamber is also formed with a centralopening or aperture 24, which will be surrounded bya suitable gland orair tight packing as desired.

IOO

Extending centrally through the device is a shaft 25 having a beltpulley 26 keyed to the upper end thereof, the said shaft passing"Vdownward through the sleeve ll, the tube 9, the opening in the lowersection 14 of the air chamber and into the step 4 in the bottom of thetub or body l. By means of the set screw l2, the air feeding device issecurely fastened to the shaft 25 and rapidly revolved thereby throughthe medium of the belt pulley 26 which is adapted to be encircled by asuit-able belt from a motor or other suitable power. The upper end ofthe'shaft 25 maybe suitably supported in a framework 27 located abovethe churn. y

The air drawn inward through the tube 9 by the rapid rotation of thesame, will be carried down into the air chamber and forced out of theperipheral openings thereof centrifugally thereby striking the cream andthoroughly penetrating the same will break the particles or globulesthereof and force it against the side of the tub or body. The whirl ormotion of the cream Will be greatly increased, and the tendency will beto drive the same outward from the air chamber, and against the breakers5 by which operation the process of making butter is exceptionallyfacilitated and quickened.

By means of the adjustabilit'y of the airchamber and the tube on theshaft which passes centrally through the same, the said air-chamber andtube may be raised or lowered to'adjust the same to a larger or smalleramount of cream or milk.

Having thus describeduthe invention, what is claimed as new isl. In achurn, the combination of abody of cylindrical form, and breakersremovably secured to the inner side thereof in diagonal linesapproximating a vertical plane and having slots in the rear portions ofthe same intermediate of the length thereof, the lower ends of each thesaid breakers being tapered to form a close fitting at the bottom of thebody and avoid too much projection, a series of eyes secured to theinner sides of the said body, and catch-pins depending from the upperportions of said slots in the breakers and adapted to removably engagethe aforesaid eyes, said pins being so arranged as to closely hold thebreakers against the inner side of the said body, substantially asdescribed.

2. In a churn, the combination of a body and a centrifugal air feedingdevice mounted therein and consisting of a tube with an upper open end,and having an air chamber at the lower end thereof constructed ofseparable sections with peripheral openings therein, situateddiametrically opposite to each other land having a part thereof'arranged in each section in such manner as to align and open in reversedirections, substantially as described.

3. In achurn, the combination of a centrifugal air feeding device havinga tube open at its upper end and formed with an air chamber at its lowerend having peripheral air openings, and interlocking pins and slots inthe opposite parts thereof, and a shaft eX- tending centrally throughsaid air feeding device and secured thereto for the purpose of rotatingthe same, substantially as described.

In testimony that I claim the foregoing as my own l have hereto affixedmy signature in the presence of two witnesses.
